The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is
already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep
state.
•
The watch will not enter a sleep state while it is in the Stopwatch Mode or
Countdown Timer Mode.
To recover from the sleep state
Move the watch to a well-lit area or press any button.

If your Home City Code setting is this:
LIS, LON, MAD, PAR, ROM, BER, STO, ATH,
MOW
HKG, BJS
TPE, SEL, TYO
HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, YYT
Important!
•
The areas covered by MOW, HNL and ANC are quite far from the calibration signal
transmitters, so certain conditions may cause reception problems.
•
When HKG or BJS is selected as the Home City, only the time and date are
adjusted according to the time calibration signal. You need to switch manually
between standard time and daylight saving time (DST) if required. See "To
configure Home City settings" (page E-42) for information about how to do this.

To get ready for a receive operation
1. Confirm that the watch is in the Timekeeping Mode. If it isn't, use C to enter the
Timekeeping Mode (page E-38).
2. The antenna of this watch is located on its 12 o'clock side. Position the watch with
12 o'clock facing towards a window as shown in the nearby illustration. Make sure
there are no metal objects nearby.

3. What you should do next depends on whether you are using Auto Receive or
Manual Receive.
•
Auto Receive: Leave the watch over night in the location you selected in step 2.
See "Auto Receive" below for details.
•
Manual Receive: Perform the operation under "To perform manual receive" on
page E-29.
Auto Receive
•
With Auto Receive, the watch performs the receive operation each day
automatically up to six times (up to five times for the Chinese calibration signal)
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode
time). When any receive operation is successful, none of the other receive
operations for that day are performed.
•
When a calibration time is reached, the watch will perform the receive operation
only if it is in the Timekeeping Mode or World Time Mode. The receive operation is
not performed if a calibration time is reached while you are configuring settings,
while a countdown timer operation is in progress, or while the hands have been
moved for easier viewing of the digital dials (page E-80).

Operation
Digital dials are off, but all functions are
enabled.
Hour and minute hands stop at
12 o'clock. All functions are disabled,
but timekeeping is maintained.
The watch can receive the signal from the
transmitter located here:
Anthorn (England), Mainflingen (Germany)
Shangqiu City (China)
Fukushima (Japan), Fukuoka/Saga (Japan)
Fort Collins, Colorado (United States)
Chinese Signal
500 kilometers
Changchun
Beijing

•
Signal reception normally is better at
night.
•
The receive operation takes from three
to eight minutes, but in some cases it
can take as long as 16 minutes. Take
care that you do not perform any
button operation or move the watch
during this time.
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See "Configuring Current
Time and Date Settings Manually" (page E-48) for more information.
This section explains how the watch updates its time settings when the city code
selected as the Home City is in Japan, North America, Europe, or China, and is one
that supports time calibration signal reception.

The Anthorn signal is receivable
within this area.
•
Even when the watch is within range of a transmitter, signal reception may be
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the influence of the
conditions listed above becomes even greater.
•
Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with
reception.
– Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
– Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
– Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
– Shangqiu (China) transmitter: 500 kilometers (310 miles)
•
As of July 2016, China does not use Daylight Saving Time (DST). If China does go
to the Daylight Saving Time system in the future, some functions of this watch may
no longer operate correctly.
•
Signal reception may be difficult or even impossible under the conditions described
below.

You can use the procedure under "To turn auto receive on and off" (page E-34) to
enable or disable auto receive.

A signal level indicator (L1, L2, or L3, see page E-32)
appears in the lower digital dial after reception starts.
Do not move the watch or perform any button operation
until GET or ERR appears in the right digital dial.
